Snowden takes a bullet to the head. What's your armchair theory?

A word of advice: do not formulate your views on international espionage after watching an Alan J. Pakula film marathon. Also, “the Mafia”? Are you living in 1963?

As far as assassination goes, Snowden has basically done all the damage he can do and the most effective thing the US can do about it is to discredit him via his irregular acts and unstable personality as much as possible. As what is being revealed is pretty much a fait accompli about which people familiar with the intelligence gathering activities were already aware (at least, to the general effort if not the extent) and the overall public response has been a resonant “meh”, the most effective thing to do with Snowden is to marginalize him.

Or Oliver Stone movies.

Snowden’s latest public pronouncements have made that job just a bit easier.

it will not be by a loud, conspicuous gunshot, but by one single salt grain size of Plutonium 210 in his Big Mac.
Its been done before. ( Alexander Litvinenko )
210Po is so radioactive, just one grain, the size of salt, emits a bright blue light about 1/2 inch in radius.
Snowden will be diagnosed with cancer, cause unknown, and will succumb 2 weeks later.

What do you mean “cause unknown?” Everybody knew what happened to Litvinenko even before he died.

There is not such thing as “Plutonium 210”. Isotopes of plutonium are plutonium-228 through plutonium-247. Alexander Litvinenko is hypothesized to have been poisoned via a small dose of polonium-210 but medical authorities have not conclusively determined this to be the case. The proximate cause of death from this kind of acute radiation poisoning would not be cancer (which generally takes months or years to develop) but rather systemic failures of the gastrointestinal, immune, and neurological systems. This method of assassination has been known to be in used by Russia and the former Soviet Union based upon radiological weapons research performed under the latter regime (and likely still being done at some level today) but is unknown for use by the CIA or other Western counterintelligence agencies, which the available information tends to indicate favoring neurological toxins.

I’d assume it was a lone nut- maybe a US right wing death-to-traitors type.

He’s already embarrassed the US enough. Assassinating him could only add to the damage. The best case scenario right now would be that he sinks into a quiet retirement in a distant country. Outside of the US, I really don’t think any other countries care enough about him to use up a bullet.

Russia and the U.S. go through an even worse period of relations then usual, after the treacherous, little piece of filth has told them everything that is of any use to them, they do a Wet Job on him.

U.S. gets the blame and everyone including Putin have a stick to beat the Americans and the wicked Westerners with.

At a cabinet meeting, Putin muttered, “Will no one rid me of this turbulent whistle blower?” and two guys paid Snowden a visit.

US assasination by Obama himself.

I’m a president in my prime
My enemies don’t distract me
The last man who attacked me
Lived a half-life so comrade come at me!

That’s insane. The US military doesn’t do that kind of thing, and doesn’t operate deeply enough in Russia to do that.

The CIA does.

correct. my error

Obama: Yeah.
Putin: Da.
Obama: Who’s this?
Putin: This is Vlad.
Obama: Vlad, what happened?
Putin: Well we…
Obama: You get it straightened out?
Putin: No, we had a problem… and uh, we tried to do everything we could.
Obama: Whaddaya mean?
Putin: Well, you know what I mean. He’s gone, and we couldn’t do nothing about it… That’s it.
Obama: Whaddaya mean? Whaddaya mean? Uh…
Putin: He’s gone. Uh, he’s gone… And that’s it.
Obama: [smashing telephone] Fuck. Can’t fuckin’ believe that, can’t fuckin’… [crying] Fuck it, fuck… the fuck…
Biden: What happened?
Obama: They whacked him. They fuckin’ whacked him.
Biden: Aw, fuck.
Obama: [cries]

Since the odds of anyone trying to assassinate him are pretty much zero (seriously, he’s not worth killing), I’d have to assume that it was the result of a sexual tryst in the airport bathroom gone awry.
